destroying an efficient seal between the jar neck 2 Claims.

This invention relates to a jar sealing device and has for the primary object the provision of a hand operated device of this character which may be readily adapted to a jar cap or closure after the application of the latter to a jar for pressing the cap or closure flange tightly and evenly against the jar gasket to prevent leakage and thereby obviate the possibility of the jar content spoiling by the admittance of air thereto.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a fragmentary side elevation, partly in section, showing a jar and closure applied thereto with the flange of said closure being forced in engagement with the jar gasket by a sealing device constructed in accordance with my invention.

Figure 2 is a top plan View illustrating the sealing device.

Figure 3 is a bottom plan view illustrating the sealing device.

Figure 4 is a fragmentary view showing the mounting of a ball to the body of the sealing device.

Referring in detail to the drawing, the numeral l indicates a fragmentary portion of a jar having a threaded flanged neck 2 on which is threaded a cap or closure 3 provided with a flange 4 to press a gasket 5 tightly to the flanged portion of the neck 2 when the cap or closure is threaded thereon. Frequently the iiange 4 is bent or does not seat evenly on the gasket thus and the cap or closure. To prevent this occurrence or leakage, a sealer 6 is employed after the application of the cap or closure to the neck.

The sealer consists of an annular body 'l having 5 one edge curved inwardly to form a hand rest 8, while its opposite edge is provided with spaced notches 9 forming parts of ball seats. Strengthening the body is a band l! offset, as shown at Il, opposite the notches 9 to cooperate therewith 10 shown in Figure 1, the balls will ride upon the 15 ange and by rotating the body with a pressure thereon irregularities of the flange 4 will be caused to disappear bringing the ange evenly and tightly against the gasket 5 so that an effective seal is provided to the neck whereby air 20 will be prevented from entering the jar and spoiling the contents thereof.

Having described the invention, I claim:

1. A jar sealing device comprising' an annular body, a hand rest for said body, said body having notches, a reinforcing band secured to the body and offset from said notches to cooperate therewith in forming seats, and balls rotatably supported by the seats.

2. A jar sealing device comprising an annular body provided with notches located in one edge thereof, balls received in said notches and protruding outwardly therefrom, and means carried by said body to retain the balls in said notches with portions thereof protruding from the notches.

FRANK B. EVERHART.
